"25-year warranty" sounds impressive. But what does it actually mean? What happens if a panel breaks in year 7? Who do you call if your inverter stops working? These are the questions that separate a good solar investment from an expensive disappointment.
There Are Three Separate Warranties — Not One
Most installers advertise "25-year warranty" as a single promise. In reality, a complete solar installation involves three distinct warranties from different parties.
1. Panel Performance Warranty (from the manufacturer)
This guarantees your panels will produce a minimum percentage of their rated output over time. The industry standard: at least 97% of rated output in year 1, and at least 85% of rated output by year 25. This covers gradual efficiency degradation — the natural, slow decline in panel output over time. It does not cover physical damage.
2. Panel Product Warranty (from the manufacturer)
This covers manufacturing defects, delamination, and physical failures of the panel itself. Standard terms: 10–12 years from reputable brands. Premium brands like Waaree, Adani, and Vikram Solar offer up to 15 years.
3. Workmanship Warranty (from your installer)
This is the installer's guarantee on their own work — the mounting structure, wiring, and installation quality. A minimum of 5 years is standard; Rayenna provides this on all installations.
Most panel warranties do not cover physical damage from external causes — hail, storms, falling objects, fire, or flood. This damage is covered by your home insurance policy, not your solar warranty. Ensure your home insurance is updated to include your solar system.
What to Do If Something Goes Wrong
- Step 1 — Check your monitoring app: Is generation low, or has it stopped? A sudden drop suggests an inverter or connection issue; a gradual decline may indicate a panel fault.
- Step 2 — Contact your installer first: They will diagnose whether it is an installation issue or a component failure and manage the claim on your behalf.
- Step 3 — If your installer is unresponsive: Contact the panel or inverter manufacturer directly with your warranty documentation.
The Lesson: Choose Your Installer as Carefully as Your Panels
The best panel warranty in the world is useless if your installer has closed down by year 6. Rayenna works exclusively with established, MNRE-approved brands and maintains a dedicated service team for all our installations.
